x86 Harddisk MBR

This is a 134 byte long MBR, Master Boot Record, for harddisks on the IBM PC and it's compatibles. It's written entirely in 8086/8088 assembly, and has extensive commenting. It's based on the 139 byte long Standard MBR by Microsoft Corp. written in 1988 for use by MS-DOS 3.30 trough Windows 95a. It's fully compatible with FDISK from MS-DOS. I'm hoping that it will be useful for someone.
